Re: hw.ncpu=1, hw.ncpuonline=1, hw.ncpufound=4
Thank you I was not aware of the security issues of hw.smt. Fortunately, things are fast enough without it, and I'm setting up a true multicore AMD system soon. On my hypothesis about CPU usage competition, I was using "interrupt" in the sense that doesn't involve computers. For example, suppose that I first run something that outputs its processing as it processes, like nmh scan(1) or playing music with mpv(1). Second, in the middle, I run something that uses the filesystem a lot, like a borg(1) backup. The first thing's output will stop for a moment while the second thing runs. Best salutations, Ipsen

The word 'interrupt' is overloaded in computing and what you saw may be a real problem with device support, or it may be completely innocuous, something which you should be ignoring. Philip Guenther

hw.ncpu=1, hw.ncpuonline=1, hw.ncpufound=4
My hw.ncpu and hw.ncpuonline are less than my hw.ncpufound. I tried setting hw.smt, but that alone was apparently not enough. What should I do if I want to use all 4 CPUs? Also, now that I have realized this, I have a theory about a related issue, and I would like to know how I can debug it. I am using softraid CRYPTO, and I have found that accessing the disk with one process will interrupt the other processes accessing the disk. Now I wonder this happens because the sole core must switch encryption/decription processes for the different files. How could I determine whether this is indeed happening? More hardware information follows.
